Secondary Factors

Repetitive Strain Injuries are unlikely to have one single cause. In most cases, a mix of factors will combine to result in an RSI-type condition. Some of these factors, the primary factors, are mainly to do with the environment. However there will usually also be some secondary factors, which may be personal to the individual.

Secondary causes of RSI may include (but are not limited to):

• Predisposition.
  Factors such as age, intrinsic strength, and general health, may all contribute to differing levels of tolerance to repetitive or prolonged strain in individuals.
  
• Stress.
  Stress makes muscles and soft tissues tense up, and when they tense up, they are more likely to be injured. Both physical and social stressors at work may contribute to this process.
